title: [A late-onset case of nonconvulsive status epilepticus of generalized epilepsy].
abstract: We report a 78-year-old woman who had episodes of nonconvulsive status epilepticus (NCSE) with dizziness. At 75 years of age, she had first seizure, but was not well examined. At 78 years of age, she had brief myoclonic jerks of her arms, soon after awakening, in May. She suffered from strong dizziness and was admitted in our hospital at the end of June. The symptoms regressed with bed rest in few days and she was discharged. However, she was admitted again with dizziness in the middle of July. There were no myoclonic jerks of her arms or legs and she could converse and interact normally, but was slightly disoriented (JCS: 2). Blood test, Cerebrospinal fluid analyses and brain MRI were normal. An EEG showed frequent intermittent generalized multiple spikes and slow wave complexes and a 3-4 Hz generalized spike and slow wave complexes every 2-4 seconds during whole 20 minutes record. Intravenous injection of 5 mg diazepam terminated status immediately. Thereafter, she was treated with sodium valproate (400 mg/day). Her symptoms improved, and interictal epileptic discharges extremely decreased. Late-onset NCSE of generalized epilepsy is rare. We discussed this case as an important case for diagnosis of NCSE with subtle symptom of dizziness.
